To all whom it may concern:

' Boats, of which the following is a specifica- 'tion.

This invention relates to certain new and useful improvements in manually propelled boats.

The primary object of the present invention is to provide, a manually propelled boat I with driven and steering wheels carried by thebottom thereof whereby the boat may be caused tob e driven over land as a manually propelled vehicle.

A further object of the invention is to' provide a device of the character disclosed in which'there is provided a unitary driving device 7 for a boat structure operating a water propeller screw and lan d wheels.

V anism Within the boat adapted selectively to drive a water propeller screw and land A still further object of the invention is to provide a boat adapted for use in waten and'on land with manually operated mechwheels.

the above general. objects in view and others that will appear as the nature of theinvention is better understood, the same consists in the novel construction, combina tion and arrangement of parts to be hereinafter more fully described and then claimed.

' In the ac'companying drawing forming a part of this application and to whlch reference s. had hereln by like characters desig- "'nating corresponding partsthroughout the several views 1 "Figure 1 is a longitudinal sectional view ofaboat constrncted in accordance with the presentinven'tion illustrating the manually propelled operating mechanism therefor.

Fig. 2 is a top plan view thereof.

Fig. 3 is an enlarged fragmentary view of a portion of the operating mechanism illustrating the clutch mechanism between the land roller operating shaft and the power sprocket wheel.

Fig. 4 is a fragmentary detail View of the mechanism shown in Fig. 3 in top plan, and

Fig. 5 is a sectional view of a portion of the clutch mechanism.

Referring more in detail to the accompanying drawing, the reference numeral 10 designates the hull of a boat that is adapted to besupported by land; wheels 11 and 12,

the wheels 11 being forwardly positioned and adapted to be driven by mechanism to be later described while the wheel 12 is rearwardly positioned and is adapted to be sh fted to const tute a steering wheel.

Thestern of the boat has the bottom thereof angularly disposed as at 13, to'provide a space beneath the boat for the rudder carried by theshaft'15 that is journaled in an angular portion 13 of the boat teas, upper end and is supported at its lower end in the vreawardlv extending bracket 16. A standard 17 is arranged withintheboat 10 and has a journal bear-' ing at its upper. end within which the pro peller shaft 18' is journaled, the propeller shaft extending, through the rear end of the 111311 as is clearly shown in Fig. 1 with the screw propeller 19 fixed thereon between the rear end of the hull and the rudder 1%.

The operating mechanism for the driven land wheels 11 and the propeller 19 is arranged within the boat 10 and includes in detail a supporting frame comprislngvertical standards 20 carrying at their upper ends journal bearings 21 that are connected by a yoke 22. y A shafti23iextends through the bearings 21 upon the standards 20 and has the lower end thereofprojecting through i the bushings24 upon .the' boat bottom with the extreme projecting end 25 thereof carrying a beveled gear wheel 26 for engagement wlth a s milar wheel 27 upon the axle shaft 28 for supporting the driven wheels 11. The ,collar, 23 for1n ng oneof the elements of alclu'tch is mounted for rotatioiriipoii the ep'peaend of the sh'aft 23 betweenthc bearings 21 and has fixed thereto a beveled pinion 30. The other element 31 of the clutch is. splined I on the shaft I 23 between l the bearings 21 and is engaged by the spring 32 to be normally held in engagement with the clutch sleeve 29. Means is provided for shifting the clutch element 31 and includes a lever 33 pivoted as at 34 to the yoke '22 with the lower end of the lever engaging the clutch element 31 at the point 35. A

pawl and ratchet mechanism 36 is carried clutch element 31 is shifted by the pedal 37 carried by the lever, the said pawl and ratchet mechanism will hold the clutch in by the lever 33 and yoke 22, and when the portion 39 and a forward forked portion ll). A cross bar ll extending between the sides of the boat 10 supports the rearwardly projectingportion 39 of the frame while the forwardly projecting forked portion has the left legthereof extending to the adjacent bearing 21 while the right leg thereof extends to the forward bearing 21 as shown in Fig. f. A sprocket wheel as is fixed to a crank shaft as journaled between the fork 40 while pedals 4a are carried by the outer projecting ends of the crank. A beveled gear wheel is fixed to one side face of the sprocket wheel as and is adapted to remain in constant mesh with the beveled pinion 80 upon the shaft A transversely extending shaft 4-6 arranged adjacent the standard 17 supports a beveled gear l? which is in mesh with the beveled gear l8 upon the propeller shaft 18. A sprocket wheel 49 is fixed to the shaft and is driven by the sprocket wheel as through the medium of the sprocket chain 50.

The steering mechanism includes a steering post 51 having handle bars 52 at its upper end and carrying a cross arm 53 adjacent its lower end which has a cord connection 5a with a cross arm 55 upon the vertical journal bearing 56 for the steering wheel 12. Another cross arm 57 is carried by the steering post 51 adjacent the upper endthereof and is connected to a cross arm 58 upon the shaft 15 of the rudder i l, by the connecting cords 59 which pass over guide pulleys 60.

The operator being upon the seat 38, operates the pedals ea and imparts rotary motion to the sprocket wheel l2 which is transmitted to the propeller 19 by the chain and gear connections above described. By shifting the steering shaft 51 by the. handles 52 the rudder 14: maybe moved to the desired side for purposes of steering the boat in a prescribed direction. l/Vith the clutch elements 29 and 31 connected as shown in Fig. 3, power from the sprocket wheel 42 is communicated to the shaft J3 by the gears 30 and 45, which motion is communicated to the driven wheels 11' by the beveled gears 26 and 27 and the shaft axle 28. The rear steering wheel 12 is shifted in an obvious manner upon movement of the handle bars 52,

While the form of the invention herein shown and described is what is believed to be the preferable embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction without departing from the spirit and scope of the invention as hereinafter claimed.

ll hat I claim as new is l. A manually propelled boat including a hull, supporting wheels therefor, a shaft journaled in said hull, a propeller shaft journaled in said hull, a screw propeller upon the outer projecting end of said propeller shaft, manually operable means for said propeller shaft and first named shaft, connecting means between the first named shaft and the forward supporting wheels, a rudder, and means for simultaneously shifting the rudder and the rear supporting wheel.

A device of the class described comprising a boat, a driven shaft journaled therein, a two part clutch member carried by said shaft, a beveled pinion carried by one of the clutch parts, a seat supporting frame mounted. in said boat, a relatively large sprocket wheel journaled in said frame, a beveled gear wheel carried thereby in mesh with said beveled pinion, a shaft j ournaled transversely of the boat, a relatively small sprocket wheel thereon having a chain connection with the large sprocket wheel,

a propeller shaft and propeller carried thereby journaled in said boat, meshing gears carried by the propeller shaft and the said transverse shaft, a rudder, a steering wheel, means for shifting the rudder and steering wheel, driven wheels, and operative connections between the first named shaft and driven wheels.

In testimony whereof l affix my signature.
